History is on McSally's side, as Arizona has not elected a Democratic senator since the late 1980s.
Republicans are trying to defend the seat vacated by retiring GOP senator Jeff Flake, whose persistent criticism of Trump made him unpopular with conservative voters. She's played up her allegiance to Trump but faces two outspoken conservative opponents: Former state Sen.
Their presence in the race forced McSally, who previously criticized Trump on occasion and has refused to say whether she voted for him in 2016, to position herself as a defender of Trump's agenda. The news comes just as another prominent political figure, Hillary Clinton, filed in court to initiate a special election, with her facing Arpaio in a one-on-one showdown. "It's a choice between a doer and a talker, between a patriot and a protester". She ran an ad to that effect last week. When the senator was first diagnosed with brain cancer, Ward said he should step down so she could take his place.
In a statement, Sinema mentioned McCain, who was known for bucking his party. When McCain's family said last week that he was discontinuing medical treatment, Ward speculated in a later-deleted Facebook post that the announcement was meant to hurt her campaign for Flake's seat. "It's up to all of us to follow his lead of always putting country over party", the Democrat said.
She continued: "Tonight, we look ahead and continue fighting to uphold the values we all share: a fair shot at the American dream and an unwavering commitment to the Arizona we love". However, Democrats might have another worry in Arizona. Television ads have already bombarded Arizona residents throughout the summer months, and a competitive general election is likely to draw in millions of dollars in outside spending for television ads and other campaigning.
Few returning Republicans have displayed much appetite for taking on McCain's role as a legislator willing to openly challenge the scandal-plagued president. McSally, Ward and Arpaio all campaigned on their various connections to Trump during the primary. And she must generate that support without alienating moderates in a state that Trump carried, but with less than 50 percent of the vote.
Both parties have their sights on flipping two Arizona House seats in November as well. "She's very charming. She's warm". On the Republican side, the endorsement from the Miami Herald could propel former Doral councilwoman Bettina Rodriguez Aguilera, who claims to have been abducted by aliens, to a stronger-than expected finish as she and several other Republicans try to catch front-runner Maria Elvira Salazar, a former TV reporter.
Both Senate candidates have compelling personal stories.
"Congresswoman McSally has spent this long, nasty intra-party fight burning her campaign's resources and squandering her credibility with the voters who will decide this election", said David Bergstein, a spokesman for the Democratic Senatorial Campaign Committee.
Sinema grew up poor - her family lived for three years in an abandoned gas station without running water and relied on food stamps for a while. With one notable exception, it was mostly a good night for front-runners.
